We design jaw profiles for virtually every popular jaw crusher

Jaw crusher manufacturers generally offer a very limited choice of designs. Most do not produce their own jaw plates, but rely on outside foundries.

In contrast, Columbia Steel is a replacement parts specialist, with over a century of engineering and manufacturing experience. Our customers have proven in the field that the right jaw plate design can make a dramatic difference, depending on the application. We have many case histories in which wear life increases of 50% are common, and some in which wear life has increased up to 300%.
